We offer a wide range of grips and adapters compatible with stringent alignment requirements, that allow tensile and or compression testing without having to remove the primary grips and therefore compromising alignment. These grips are also compatible with chambers for non-ambient testing and advanced extensometry solutions for most accurate strain measurements.
Reliable, Precision Aligned Frames with Debris Protection Pre-loaded bearings and precision ball screws, a thick crosshead and base beam, and low-stretch drive belts contribute to better performance and minimize the energy stored during a test, reducing damage from shock-loads at the end of the test. Seals and filters protect your systems’ electronics from harmful composite dust and debris.

|Ensure Audit Compliance
Precision Alignment to Nadcap Our EM Frames’ very solid design ensures minimal compliance and bending, achieving Nadcap alignment requirements without an alignment cell. For more complex test machine configurations the same machine can easy be configured with an alignment cell and software to minimize bending.

Alignment is critical when testing composites. Instron testing machines use precision guidance columns along with adjustable AlignPRO™ alignment fixtures to meet and maintain the highest levels of alignment demanded by the aerospace industry, and help you achieve Nadcap compliance.
Our environmental chambers will enable you to test the mechanical properties of composite materials and components over a wide range of temperatures from -150 °C up to +600 °C, controllable in Bluehill Universal. The chambers are equipped with multipaned windows to be able to view the test and enabling the use of non-contact extensometry. Rapid heat up and cool down times improve productivity of operators and throughput of test specimens.View Chambers
Extensometers are used extensively for composites due to their need for precise strain measurement. Instron builds and calibrates contacting and non-contacting extensometers that have been specifically designed for testing composite materials. Instron systems also play nicely with strain gauges.View Extensometers
The Bluehill® Universal Composite Module includes many composite testing standards to make testing simple and more consistent across many different systems and labs.
To Perform the Most Common Test Types for Composites
